Re: Forcing modperl processes to restart after N requestsby McA (Priest)
|on Oct 12, 2012 at 18:03 UTC||Need Help??|
The simplest solution is to let Apache handle it: There is a configuration parameter MaxRequestsPerChild. On default installations it's set relativly high. Tweak it for you mod_perl centric processes.
Look at http://perl.apache.org/docs/1.0/guide/performance.html#Measuring_the_Memory_of_the_Process for some hints on memory usage.
Look for documentation of $r->child_terminate. With that method you can force the Apache child to exit gracefully at the end of the whole request lifetime. Combined with a process global counter you could implement an own controlled way of exiting after an certain count of requests. With this way you could be sure that a certain amount of perl handled requests were served (using Apache for static and dynamic content).
P.S.: mod_perl mailing list is the right target for these questions. Thorsten Förtsch regularly answer fast and very competent. (http://foertsch.name/)
